DIVERTER VALVE ASSEMBLY
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims priority from and the benefit of U.S.
Provisional Application
Serial No. 63/074,104, entitled "DIVERTER VALVE ASSEMBLY", filed September
3,2020,
which is hereby incorporated by reference in its entirety.
BACKGROUND
[0002] This section is intended to introduce the reader to various aspects
of art that may be
related to various aspects of the presently described embodiments. This
discussion is believed to
be helpful in providing the reader with background information to facilitate a
better
understanding of the various aspects of the present embodiments. Accordingly,
it should be
understood that these statements are to be read in this light, and not as
admissions of prior art.
[0003] In order to meet consumer and industrial demand for natural
resources, companies
search for and extract oil, natural gas, and other subterranean resources from
the earth. Once a
desired subterranean resource is discovered, drilling and production systems
are employed to
access and extract the resource. These systems may be located onshore or
offshore depending on
the location of a desired resource. For example, in surface operations,
hydrocarbon fluids such
as oil and natural gas are obtained from a subterranean geologic formation,
referred to as a
reservoir, by drilling a well that penetrates the hydrocarbon-bearing geologic
formation. In
various surface applications (e.g., fracking applications, etc.) and other
well applications, a
diverter valve may be used to direct fluid flow from a single source to a
selected target
destination. For example, a diverter valve may include a single inlet and
three outlets. The inlet
may receive fluid from the single source, and each outlet may be fluidly
coupled to a respective
destination (e.g., via a respective conduit). The diverter valve may be
controlled to selectively
direct the fluid from the inlet to one selected outlet, thereby establishing
fluid flow from the
single source to a selected target destination. Unfortunately, such a diverter
valve may be
1
CA 03193782 2023-03-03
WO 2022/051367 PCT/US2021/048673
incapable of selectively directing fluid from the single source to multiple
selected target
destinations concurrently. In addition, designing and manufacturing a valve
assembly to
selectively direct fluid from the single source to multiple selected target
destinations
concurrently may be complex and costly.

[0010] FIG. 1 is a perspective view of an embodiment of a diverter valve
assembly 10. In
the illustrated embodiment, the diverter valve assembly 10 includes a first
diverter valve 12 and a
second diverter valve 12 coupled to one another. Each diverter valve includes
a housing 14 and a
rotary element disposed within the housing 14. As illustrated, the housing 14
has an inlet 16
positioned at a first longitudinal end 18 of the housing 14 (e.g., first end
of the housing along a
longitudinal axis 20 of the diverter valve 12/diverter valve assembly 10). In
addition, the
housing 14 has a subsequent diverter valve outlet positioned at a second
longitudinal end 22 of
the housing 14 (e.g., second end of the housing along the longitudinal axis
20), opposite the first
longitudinal end 18. The housing 14 also includes multiple destination outlets
24 disposed
circumferentially about the longitudinal axis 20 (e.g., disposed along a
circumferential axis 26).
In the illustrated embodiment, each housing 14 includes three destination
outlets 24 substantially
equally distributed along the circumferential axis 26. However, in other
embodiments, at least
one housing may include more or fewer destination outlets (e.g., 2, 4, 5, 6,
7, 8, or more), and/or
the destination outlets of at least one housing may have non-uniform spacing
along the
circumferential axis. Furthermore, each destination outlet 24 is formed at the
end of a respective
destination flow path 28 through the respective housing 14. In the illustrated
embodiment, each
destination flow path 28 extends along a radial axis 30 of the diverter valve
assembly 10.
However, in other embodiments, at least one destination flow path may extend
along another
3
CA 03193782 2023-03-03
WO 2022/051367 PCT/US2021/048673
suitable direction and/or route to the destination outlet. For example, at
least one destination
flow path may extend along a curved path, at least one destination flow path
may be angled
relative to the radial axis, at least one destination flow path may include
multiple sections that
are angled relative to one another, or a combination thereof
[0011] As discussed in detail below, a rotary element is disposed within
each housing 14.
The rotary element has an inlet, a target destination outlet, and a subsequent
diverter valve outlet.
The inlet of the rotary element is fluidly coupled to the inlet of the housing
14 (e.g., the inlet of
the rotary element is substantially aligned with the inlet of the housing 14
along the longitudinal
axis 20), and the subsequent diverter valve outlet of the rotary element is
fluidly coupled to the
subsequent rotary valve outlet of the housing 14 (e.g., the subsequent
diverter valve outlet of the
rotary element is substantially aligned with the subsequent rotary valve
outlet of the housing 14
along the longitudinal axis 20). In addition, the rotary element is configured
to rotate about the
longitudinal axis 20 (e.g., along the circumferential axis 26) to selectively
fluidly couple (e.g.,
align) the target destination outlet of the rotary element with a respective
destination outlet 24 of
the respective housing 14.
[0012] In the illustrated embodiment, each housing 14 has multiple threaded
recesses 32 at
the first longitudinal end 18 of the housing 14. As illustrated, each threaded
recess 32 extends
along the longitudinal axis 20, and each threaded recess 32 is configured to
receive a respective
threaded shaft 34. The threaded shafts 34 facilitate coupling the housing 14
to a flange of a fluid
source/fluid inlet conduit or to a flange of a previous diverter valve, as
discussed in detail below.
The flange may have multiple apertures, and the threaded shafts 34 may extend
through the
apertures of the flange while the flange is engaged with the housing 14. A nut
36 may be
engaged with each threaded shaft 34 to couple the flange to the housing 14. In
the illustrated
embodiment, the threaded recesses 32 are distributed about the longitudinal
axis 20 in a circular
pattern. However, in other embodiments, the threaded recesses may be arranged
in any other
suitable pattern (e.g., corresponding to the pattern of the apertures of the
respective flange).
Furthermore, while each threaded recess extends along the longitudinal axis in
the illustrated
embodiment, in other embodiments, at least one threaded recess may extend
along another
4
CA 03193782 2023-03-03
WO 2022/051367 PCT/US2021/048673
suitable direction (e.g., angled with respect to the longitudinal axis). In
addition, while threaded
recesses in the housing are used to couple the fluid source/fluid inlet
conduit or previous diverter
valve to the housing in the illustrated embodiment, in other embodiments,
other and/or additional
connection system(s) may be used to couple the fluid source/fluid inlet
conduit or previous
diverter valve to the housing. For example, in certain embodiments, the
housing may include a
flange positioned at the first longitudinal end of the housing, and the flange
may be configured to
engage a corresponding flange of the fluid source/fluid inlet conduit or
previous diverter valve.
The flange may also be configured to engage a body of the fluid source or the
housing of the
previous diverter valve.
[0013] In the illustrated embodiment, the inlet 16 of each housing 14 is
formed at the end of
an inlet flow path 38 through the housing 14. Furthermore, in the illustrated
embodiment, the
inlet flow path 38 extends along the longitudinal axis 20 of the diverter
valve assembly 10.
However, in other embodiments, the inlet flow path may extend along another
suitable direction
and/or route to the inlet. For example, the inlet flow path may extend along a
curved path, the
inlet flow path may be angled relative to the longitudinal axis, the inlet
flow path may include
multiple sections that are angled relative to one another, or a combination
thereof In the
illustrated embodiment, each diverter valve 12 includes a first end cap 40
disposed within the
inlet flow path 38. The first end cap 40 is configured to block movement of
the rotary element
along the longitudinal axis 20 through the inlet 16 of the housing 14 and to
facilitate rotation of
the rotary element about the longitudinal axis 20. In addition, the first end
cap 40 includes a
flow passage 42 extending from the inlet of the housing 14 to the inlet of the
rotary element. The
flow passage 42 is configured to direct fluid received at the inlet 16 of the
housing 14 (e.g., from
the fluid source) to the inlet of the rotary element. In the illustrated
embodiment, the first end
cap 40 has an annular recess 44 configured to receive a seal (e.g., 0-ring,
etc.). The seal is
configured to substantially block fluid from flowing out of the interface
between the housing and
the fluid source/fluid inlet conduit or the previous diverter valve. While the
first end cap 40
includes the annular recess 44 in the illustrated embodiment, in other
embodiments, the annular
recess may be omitted. Furthermore, in certain embodiments, a gasket may be
disposed between
the housing and the fluid source/fluid inlet conduit or the previous diverter
valve (e.g., alone or
CA 03193782 2023-03-03
WO 2022/051367
PCT/US2021/048673
in combination with the seal disposed within the annular recess of the first
end cap) to
substantially block fluid from flowing out of the interface between the
housing and the fluid
source/fluid inlet conduit or the previous diverter valve. Furthermore, in
certain embodiments,
the first end cap may be omitted and movement of the rotary element through
the inlet of the
housing may be blocked by other suitable device(s)/element(s) (e.g., a
protrusion of the rotary
element engaged with an annular recess in the housing along the inlet flow
path, an annular ridge
extending inwardly from the inlet flow path along the radial axis, etc.). In
such embodiments,
fluid may flow from the inlet of the housing to the inlet of the rotary
element via the inlet flow
path of the housing.
[0014] In
the illustrated embodiment, the housing 14 of each diverter valve 12 includes
a
flange 46 that forms the second longitudinal end 22 of the housing 14. The
flange 46 is
configured to facilitate coupling between the housing 14 and a subsequent
diverter valve or a
blind flange 48. Coupling the flange 46 to the housing of a subsequent
diverter valve establishes
a fluid connection between the subsequent diverter valve outlet of the housing
of the previous
diverter valve and the inlet of the housing of the subsequent diverter valve.
In the illustrated
embodiment, the flange 46 includes multiple apertures 50 configured to receive
fasteners that
couple the flange to the subsequent diverter valve or to the blind flange. In
the illustrated
embodiment, the flange 46 of the first diverter valve 52 (e.g., previous
diverter valve) is engaged
with the housing 14 of the second diverter valve 54 (e.g., subsequent diverter
valve), thereby
coupling the diverter valves to one another. Threaded shafts are engaged with
the threaded
recesses of the housing 14 of the second diverter valve 54, and the threaded
shafts extend
through respective apertures 50 of the flange 46 of the first diverter valve
52. In addition, nuts
36 are engaged with the respective threaded shafts, thereby coupling the first
diverter valve 52 to
the second diverter valve 54. While the second longitudinal end of each
housing is formed by a
flange in the illustrated embodiment, in other embodiments, the second
longitudinal end of at
least one housing may be formed by another suitable surface/component. For
example, in certain
embodiments, the flange may be omitted, and threaded recesses may be formed at
the second
longitudinal end of the housing (e.g., within a body of the housing). In such
embodiments,
6
CA 03193782 2023-03-03
WO 2022/051367 PCT/US2021/048673
threaded rods may be engaged with the threaded recesses to couple the housing
to the housing of
a subsequent diverter valve or to a blind flange.
[0015] As previously discussed, each housing 14 includes a subsequent
diverter valve outlet
positioned at the second longitudinal end 22 of the housing, and the
respective rotary element
includes a subsequent diverter valve outlet fluidly coupled to (e.g.,
substantially aligned with) the
subsequent diverter valve outlet of the housing. In certain embodiments, the
subsequent diverter
valve outlet of the housing is formed at the end of a subsequent diverter
valve outlet flow path
through the housing 14. The flow path may extend along the longitudinal axis
20 of the diverter
valve 12/diverter valve assembly 10. However, in other embodiments, the
subsequent diverter
valve outlet flow path of at least one housing may extend along another
suitable direction and/or
route to the respective subsequent diverter valve outlet. For example, the
subsequent diverter
valve outlet flow path may extend along a curved path, the subsequent diverter
valve outlet flow
path may be angled relative to the longitudinal axis, the subsequent diverter
valve outlet flow
path may include multiple sections that are angled relative to one another, or
a combination
thereof
[0016] Furthermore, in certain embodiments, each diverter valve 12 includes
a second end
cap disposed within the subsequent diverter valve outlet flow path of the
housing 14. The
second end cap is configured to block movement of the rotary element along the
longitudinal
axis 20 through the subsequent diverter valve outlet and to facilitate
rotation of the rotary
element about the longitudinal axis 20. In addition, the second end cap
includes a flow passage
extending from the subsequent diverter valve outlet of the rotary element to
the subsequent
diverter valve outlet of the housing. The flow passage is configured to direct
fluid to flow from
the subsequent diverter valve outlet of the rotary element to the subsequent
diverter valve outlet
of the housing. Furthermore, in certain embodiments, the second end cap may be
omitted and
movement of the rotary element through the subsequent diverter valve outlet of
the housing may
be blocked by other suitable device(s)/element(s) (e.g., a protrusion of the
rotary element
engaged with an annular recess in the housing along the subsequent diverter
valve outlet flow
path, an annular ridge extending inwardly from the subsequent diverter valve
outlet flow path
7
CA 03193782 2023-03-03
WO 2022/051367 PCT/US2021/048673
along the radial axis, etc.). In such embodiments, fluid may flow from the
subsequent diverter
valve outlet of the rotary element to the subsequent diverter valve outlet of
the housing via the
subsequent diverter valve outlet flow path of the housing.
[0017] As previously discussed, the blind flange 48 is coupled to the
flange 46 of the second
diverter valve 54. The blind flange 48 is configured to cover the subsequent
diverter valve outlet
of the housing 14, thereby substantially blocking fluid flow out of the
subsequent diverter valve
outlet of the second diverter valve 54. In the illustrated embodiment,
threaded shafts extend
through the apertures 50 of the flange 46 of the second diverter valve 54, and
the threaded shafts
extend through respective apertures 56 of the blind flange 48. In addition,
first nuts 36 are
engaged with first ends of the respective threaded shafts, and second nuts 58
are engaged with
second ends of the respective threaded shafts, thereby coupling the flange 46
of the second
diverter valve 54 to the blind flange 48. In embodiments in which threaded
recesses are formed
at the second longitudinal end of the housing of the second diverter valve
(e.g., and the flange is
omitted), the threaded rods may be engaged with the threaded recesses to
couple the housing to
the blind flange. In certain embodiments, a gasket may be disposed between the
flange 46 of the
housing 14 of the second diverter valve 54 and the blind flange 48 to
substantially block fluid
from flowing out of the interface between the flange 46 of the second diverter
valve 54 and the
blind flange 48. Furthermore, while a blind flange is used to block the
subsequent diverter valve
outlet of the housing in the illustrated embodiment, in other embodiments,
another suitable
blocking device (e.g., plug, seal, etc.) may be coupled to the housing to
block the subsequent
diverter valve outlet of the housing.
[0018] In the illustrated embodiment, each housing 14 has multiple threaded
recesses 60
disposed about each destination outlet 24. Each threaded recess 60 is
configured to receive a
respective threaded shaft to facilitate coupling the housing 14 to a flange of
a destination/fluid
conduit to a destination. The flange may have multiple apertures, and the
threaded shafts may
extend through the apertures of the flange while the flange is engaged with
the housing 14. A nut
may be engaged with each threaded shaft to couple the flange to the housing
14. In the
illustrated embodiment, the threaded recesses 60 are distributed about the
respective destination
8
CA 03193782 2023-03-03
WO 2022/051367 PCT/US2021/048673
outlet 24 in a circular pattern. However, in other embodiments, the threaded
recesses may be
arranged in any other suitable pattern (e.g., corresponding to the pattern of
the apertures of the
respective flange). Furthermore, while threaded recesses in the housing are
used to couple the
housing to the destination/fluid conduit to the destination in the illustrated
embodiment, in other
embodiments, other and/or additional connection system(s) may be used to
couple the housing to
the destination/fluid conduit to the destination. For example, in certain
embodiments, the
housing may include flange(s) positioned at one or more respective destination
outlet(s), and the
flange(s) may be configured to engage corresponding flange(s) of the
destination(s)/fluid
conduit(s) to the destination(s). Each flange may also be configured to engage
a body of the
destination.
[0019] In the illustrated embodiment, each housing 14 includes an annular
recess 62
disposed about each destination outlet 24, in which each annular recess 62 is
configured to
receive a seal (e.g., 0-ring, etc.). The seal is configured to substantially
block fluid from flowing
out of the interface between the housing and the respective destination/fluid
conduit to the
destination. While an annular recess 62 is disposed about each destination
outlet 24 in the
illustrated embodiment, in other embodiments, at least one annular recess may
be omitted.
Furthermore, in certain embodiments, for at least one destination outlet, a
gasket may be
disposed about the destination outlet 24 between the housing and the
respective destination/fluid
conduit to the destination (e.g., alone or in combination with the seal
disposed within the annular
recess) to substantially block fluid from flowing out of the interface between
the housing and the
destination/fluid conduit to the destination.
[0020] During operation of the diverter valve assembly 10 (e.g., during
fracking operations,
etc.), fluid (e.g., fracking fluid, etc.) enters the inlet 16 of the housing
14 of the first diverter
valve 52 and flows to the inlet of the rotary element of the first diverter
valve 52. A first portion
of the fluid flows through the target destination outlet of the rotary element
to a selected
destination outlet 24 of the housing 14 of the first diverter valve 52. The
first portion of the fluid
then flows through the selected destination outlet 24 of the housing 14 to the
target destination
(e.g., via a conduit extending between the selected destination outlet 24 and
the target
9
CA 03193782 2023-03-03
WO 2022/051367 PCT/US2021/048673
destination). As previously discussed, the rotary element is configured to
rotate about the
longitudinal axis 20 to selectively fluidly couple (e.g., align) the target
destination outlet of the
rotary element with a selected destination outlet 24 of the housing 14,
thereby enabling the fluid
to flow to the selected target destination. A second portion of the fluid
entering the inlet of the
rotary element is directed through the rotary element along the longitudinal
axis 20 to the
subsequent diverter valve outlet of the rotary element. The second portion of
the fluid then flows
through the subsequent diverter valve outlet of the housing 14 of the first
diverter valve 52 to the
inlet of the housing 14 of the second diverter valve 54.
[0021] From the inlet of the housing of the second diverter valve, the
fluid flows to the inlet
of the rotary element of the second diverter valve. The fluid then flows
through the target
destination outlet of the rotary element of the second diverter valve to a
selected destination
outlet 24 of the housing 14 of the second diverter valve 54. From the selected
destination outlet
24 of the housing 14, the fluid flows to the target destination (e.g., via a
conduit extending
between the selected destination outlet 24 and the target destination). As
previously discussed,
the rotary element is configured to rotate about the longitudinal axis 20 to
selectively fluidly
couple (e.g., align) the target destination outlet of the rotary element with
a selected destination
outlet 24 of the housing 14, thereby enabling the fluid to flow to the
selected target destination.
Flow of the fluid out of the subsequent diverter valve outlet of the housing
14 of the second
diverter valve 54 is blocked by the blind flange 48.
[0022] Because the illustrated diverter valve assembly 10 includes two
diverter valves 12,
fluid entering the inlet 16 of the housing 14 of the first diverter valve 52
may be directed to a
first selected target destination among the destinations fluidly coupled to
the destination outlets
24 of the first diverter valve 52 and to a second selected target destination
among the destinations
fluidly coupled to the destination outlets 24 of the second diverter valve 54.
In certain
embodiments, the rotary element of at least one diverter valve may be rotated
to a position that
aligns the target destination outlet of the rotary element with a solid
portion of the housing,
thereby blocking fluid flow to all of the destinations fluidly coupled to the
destination outlets of
the diverter valve. Furthermore, in certain embodiments, the rotary element
may include
CA 03193782 2023-03-03
WO 2022/051367 PCT/US2021/048673
multiple target destination outlets (e.g., less than the number of destination
outlets of the
respective housing). In such embodiments, the target destination outlets of
the rotary element
may be fluidly coupled to (e.g., substantially aligned with) multiple
destination outlets of the
respective housing to enable the fluid to flow to multiple selected target
destinations.
[0023] Because the subsequent diverter valve outlet of the housing of a
previous diverter
valve may be fluidly coupled to the inlet of the housing of a subsequent
diverter valve, the
diverter valve assembly may include any suitable number of diverter valves, in
which multiple
destinations are fluidly coupled to each diverter valve. For example, in the
illustrated
embodiment, the diverter valve assembly includes two diverter valves. However,
in other
embodiments, the diverter valve assembly may include 1, 3, 4, 5, 6, 7, 8, or
more diverter valves.
For example, in a diverter valve assembly having a single diverter valve, the
blind flange may be
coupled to the flange of the single diverter valve. Because the diverter valve
assembly may
include any suitable number of diverter valves, the diverter valve assembly
may be used in
various applications/systems having varying numbers of destinations. As a
result, the design and
manufacturing costs of the diverter valve assembly may be significantly
reduced, as compared to
particularly designing a different diverter valve/diverter valve assembly for
each
application/system. In addition, because each diverter valve within the
diverter valve assembly
may be substantially the same, the design and manufacturing costs may be
further reduced.
[0024] FIG. 2 is a bottom perspective view of a portion of a diverter valve
12 of the diverter
valve assembly of FIG. 1. As previously discussed, the housing 14 includes a
subsequent
diverter valve outlet 64 positioned at the second longitudinal end 22 of the
housing, and the
rotary element includes a subsequent diverter valve outlet fluidly coupled to
(e.g., substantially
aligned with) the subsequent diverter valve outlet 64 of the housing 14. In
the illustrated
embodiment, the subsequent diverter valve outlet 64 of the housing is formed
at the end of a
subsequent diverter valve outlet flow path 66 through the housing 14. In the
illustrated
embodiment, the flow path extends along the longitudinal axis 20 of the
diverter valve
12/diverter valve assembly. However, in other embodiments, the subsequent
diverter valve
outlet flow path may extend along another suitable direction and/or route to
the respective
11
CA 03193782 2023-03-03
WO 2022/051367 PCT/US2021/048673
subsequent diverter valve outlet. For example, the subsequent diverter valve
outlet flow path
may extend along a curved path, the subsequent diverter valve outlet flow path
may be angled
relative to the longitudinal axis, the subsequent diverter valve outlet flow
path may include
multiple sections that are angled relative to one another, or a combination
thereof
[0025] In the illustrated embodiment, the diverter valve 12 includes a
second end cap 68
disposed within the subsequent diverter valve outlet flow path 66 of the
housing 14. The second
end cap 68 is configured to block movement of the rotary element along the
longitudinal axis 20
through the subsequent diverter valve outlet 64 and to facilitate rotation of
the rotary element
about the longitudinal axis 20. In addition, the second end cap 68 includes a
flow passage 70
extending from the subsequent diverter valve outlet of the rotary element to
the subsequent
diverter valve outlet 64 of the housing 14. The flow passage 70 is configured
to direct fluid to
flow from the subsequent diverter valve outlet of the rotary element to the
subsequent diverter
valve outlet 64 of the housing 14. In the illustrated embodiment, the second
end cap 68 has an
annular recess 72 configured to receive a seal (e.g., 0-ring, etc.). The seal
is configured to
substantially block fluid from flowing out of the interface between the
housing 14 (e.g., the
flange 46 of the housing 14) and the housing of the subsequent diverter valve
or the blind flange.
While the second end cap 68 includes the annular recess 72 in the illustrated
embodiment, in
other embodiments, the annular recess may be omitted. Furthermore, in certain
embodiments, a
gasket may be disposed between the housing (e.g., the flange of the housing)
and the housing of
the subsequent diverter valve or the blind flange (e.g., alone or in
combination with the seal
disposed within the annular recess of the second end cap) to substantially
block fluid from
flowing out of the interface between the housing (e.g., the flange of the
housing) and the housing
of the subsequent diverter valve or the blind flange. Furthermore, in certain
embodiments, the
second end cap may be omitted and movement of the rotary element through the
subsequent
diverter valve outlet of the housing may be blocked by other suitable
device(s)/element(s) (e.g., a
protrusion of the rotary element engaged with an annular recess in the housing
along the
subsequent diverter valve outlet flow path, an annular ridge extending
inwardly from the
subsequent diverter valve outlet flow path along the radial axis, etc.). In
such embodiments,
fluid may flow from the subsequent diverter valve outlet of the rotary element
to the subsequent

diverter valve outlet of the housing via the subsequent diverter valve outlet
flow path of the
housing.
[0026] FIG. 3 is an exploded perspective view of a portion of a diverter
valve 12 of the
diverter valve assembly of FIG. 1. As previously discussed, the diverter valve
12 includes the
rotary element 74 configured to be disposed within the housing 14, such as
within a central
cavity 76 of the housing 14. As illustrated, the cavity 76 extends through the
housing 14 from
the inlet 16 to the subsequent diverter valve outlet along the longitudinal
axis 20. The cavity 76
includes the inlet flow path 38 and the subsequent diverter valve outlet flow
path. In addition,
each destination flow path 28 extends to the cavity 76, thereby fluidly
coupling the respective
destination outlet 24 to the cavity 76.
[0027] Furthermore, the rotary element 74 has an inlet 78, a target
destination outlet 80, and
a subsequent diverter valve outlet 82. The inlet 78 and the subsequent
diverter valve outlet 82
are fluidly coupled via a cavity 84 extending through the rotary element 74
along the
longitudinal axis 20. In addition, the target destination outlet 80 is formed
at the end of a target
destination flow path 86, which extends from the cavity 84. Accordingly, the
target destination
flow path 86 fluidly couples the target destination outlet 80 to the cavity
84. The inlet 78 of the
rotary element 74 is configured to fluidly couple to (e.g., align with) the
inlet 16 of the housing
14, and the subsequent diverter valve outlet 82 of the rotary element 74 is
configured to fluidly
couple to (e.g., align with) the subsequent diverter valve outlet of the
housing 14. Furthermore,
the rotary element 74 is configured to rotate about the longitudinal axis 20
to selectively fluidly
couple (e.g., align) the target destination outlet 80 with a respective
destination outlet 24 of the
housing 14. While the illustrated rotary element 74 has a single target
destination outlet 80 in the
illustrated embodiment, in other embodiments, the rotary element may include
multiple target
destination outlets.
[0028] In the illustrated embodiment, the diverter valve 12 has an actuator
88 configured to
drive the rotary element 74 to rotate. In certain embodiments, each diverter
valve of the diverter
valve assembly includes a respective actuator to facilitate independent
control of the respective
13
CA 03193782 2023-03-03
WO 2022/051367 PCT/US2021/048673
rotary elements. However, in other embodiments, the diverter valve assembly
may include an
actuator configured to drive multiple rotary elements (e.g., all of the rotary
elements of the
diverter valve assembly) to rotate together. The actuator 88 may include any
suitable device(s)
configured to drive the rotary element 74 to rotate, such as a hydraulic
motor, a pneumatic motor,
a worm gear, a linear actuator, a hydraulic cylinder, a pneumatic cylinder, a
gear assembly, a belt,
a chain, a wheel, a sprocket, another suitable driving element, another
suitable movement
redirection element, or a combination thereof. For example, in certain
embodiments, the actuator
may include a hydraulic motor coupled to the housing and a worm gear extending
through the
housing from the hydraulic motor to the rotary element. By way of further
example, a protrusion
may be coupled to the rotary element, and the protrusion may extend through a
slot in the
housing. A hydraulic cylinder of the actuator may be coupled to the protrusion
and configured to
drive the rotary element to rotate. Furthermore, in certain embodiments, the
actuator may
include a handle coupled to the rotary element (e.g., and extending through
the housing) to
facilitate manual rotation of the rotary element.
[0029] While each outlet and flow path/passage of the diverter valve
assembly disclosed
above with reference to FIGS. 1-3 has a circular shape/cross-section in the
illustrated
embodiment, in other embodiments, at least one outlet and/or flow path/passage
may have
another suitable shape/cross-sectional shape (e.g., polygonal, elliptical,
etc.). Furthermore, the
diverter valve assembly disclosed above with reference to FIGS. 1-3 may be
used for various oil
and gas applications, such as controlling the flow path of fracking fluid. The
diverter valve
assembly disclosed above with reference to FIGS. 1-3 may also be used for any
other suitable
application to control a fluid flow path through a system. In addition, while
each diverter valve
includes a single rotary element in the illustrated embodiment, in other
embodiments, at least one
diverter valve may include multiple rotary elements (e.g., arranged along a
longitudinal axis and
longitudinally aligned with a respective set of housing destination outlet
passages).
[0030] In addition, while the inlet and the subsequent diverter valve
outlet are positioned at
respective longitudinal ends of each housing and each rotary element in the
illustrated
embodiment, in other embodiments, the inlet and/or the subsequent diverter
valve outlet of at
14
CA 03193782 2023-03-03
WO 2022/051367 PCT/US2021/048673
least one housing and/or at least one rotary element may be positioned in
another suitable
location. For example, in certain embodiments, the inlet and/or the subsequent
diverter valve
outlet of at least one rotary element may be positioned along a
circumferential surface of the
rotary element (e.g., in which the inlet/subsequent diverter valve outlet is
fluidly coupled to an
annular cavity within the housing). Furthermore, in certain embodiments, the
housing of at least
one diverter valve may have a shape (e.g., curved, angled, etc.) that
establishes any suitable
angle between the inlet and subsequent diverter valve outlet (e.g., the
respective inlet flow path
and the respective subsequent diverter valve outlet flow path may be angled
relative to one
another). Furthermore, while each rotary element is configured to rotate about
the longitudinal
axis of the respective diverter valve/diverter valve assembly in the
illustrated embodiment, in
other embodiments, at least one rotary element may be configured to rotate
about another
suitable axis. In addition, while the diverter valve housings are configured
to be aligned with
one another along the longitudinal axis of the diverter valve assembly in the
illustrated
embodiment, in other embodiments, at least two housings may be offset from one
another and/or
angled relative to one another, thereby establishing a local longitudinal axis
for each diverter
valve. In certain embodiments, the subsequent diverter valve outlet of the
housing of a previous
diverter valve may be fluidly coupled to the inlet of the housing of a
subsequent diverter valve
with a conduit/hose.
